What Hijacker Means And How It Can Affect
Hijacker it is one of the many types of malware that can compromise us when surfing the Internet. Its mission is to modify the configuration of a web browser, such as Google Chrome or Mozilla Firefox. This threat is also known as a browser hijacker.
But it goes beyond the browser itself. also can hijack web pages, domains or DNS. This is attached to the browser settings or data to log in. It is an attack that can modify the way in which users, the victims in short, see a website.
For example they could modify DNS of a web domain. In this case, the victim enters a page, such as RedesZone, and is automatically redirected to a totally different one. In this way they could sneak malware, be a site that is actually Phishing and simply seeks to steal passwords, etc.
Therefore, Hijacker is basically an attack against the browser, against a website or the DNS whose mission is to modify what users receive. If we go back to the example of the browser, when the victim logs in, this data would end up on a server controlled by cybercriminals. The same if we enter a website that has been previously attacked.
A hijacker could even install a malicious plugin in our system that paralyzes the antivirus. In this way, when scanning we would not find any threat, which would be an even greater problem to avoid being a victim.
In short, we have different types of hijacker:
- Browser: is the most common type that can be present in any browser. It could seriously damage security.
- Websites– They can hijack a website and install malicious add-ons to steal visitor information.
- DNS: consists of modifying the DNS so that the victim is redirected to another malicious website.
- Session– In this case the attacker could steal the login data, such as credentials or passwords.
How to Avoid Being Victims of a Hijacker Attack
We have seen what a hijacker attack consists of. It is a very important problem that could compromise our security and privacy when surfing the net. It could put our personal data, passwords and, ultimately, the proper functioning of the equipment at risk. But luckily we can always take into account some tips to avoid being victims of this kind of problem.
Of course, it must be taken into account that several parts come into play here. On the one hand there is the security of our equipment, to prevent the entry of malware, but on the other hand there is the security of the pages we visit, which does not depend on us.
There are many options we have to install security tools in our teams. We are talking, for example, of an antivirus, which can help us detect and eliminate the entry of malware that could compromise us. There are many types of malicious software and it is always a good idea to detect them as soon as possible.
But also, other programs such as firewalls could help us avoid accessing web pages that have been modified. They would alert us in case of entering a site that has changed the IP address. Therefore, it would defend us against DNS hijacker attacks. We have many programs, both free and paid, and also for all types of operating systems.
Keep equipment up to date
Of course it is also essential to have the properly updated equipment. On many occasions vulnerabilities can arise that are exploited precisely by hackers who could attack computers.
This makes it very important to install all software-level updates that may exist. We must correct any failure that may arise. It is the developers themselves who launch these new versions and we must apply them in browsers, programs that we use, operating systems …
Protect our website
If we have a web page and we want prevent hijacker attacks we must protect it adequately. We must register the domain on a website that adds protection against hijacking. This is essential today when creating a website, since otherwise we would be giving an insecure service to visitors.
Therefore, if we are responsible for a website and we want to avoid this type of problem, we must protect it adequately. We must prevent those data breaches and failures that hackers could exploit to achieve their goals.
Take a good look at the URL when entering a website
If we are home users and we want to avoid being victims of DNS hijacking when entering a website, we must observe the URL very well that appears in the browser. If we find any change, any sign that tells us that this site is not safe, it is not the original, we should leave the page and of course never expose our data.
Simply by taking a good look at the URL, the address of the site, we can verify that we are on a legitimate page or it could be a scam. It is one more tip to keep in mind to avoid being a victim of the hijacker threat. It is undoubtedly one of the most common problems of this type of threat. It is also one of the most visible points that we can see.
Of course the common sense must be present at all times. Many types of attacks, and also those related to hijacker, are going to require user interaction. For example, downloading a suspicious file from the Internet, opening an e-mail that we have received that contains a dangerous attachment, filtering information inadvertently on public websites …
All this, all these small flaws, could compromise our security and favor these types of threats. Therefore, we must avoid mistakes, maintain common sense at all times and reduce risk as much as possible.
In short, Hijacker is one of the threats that we can find when browsing the Internet. It could pose a very significant problem for our security and privacy. This makes it necessary to take action, follow advice and recommendations like the ones we have given in this article. The goal, once again, is to protect our equipment and not have any problems on the network.
